The P-737 specimen Z-stage is a new member in a large family of products for microscope automation. Specifically designed for research microscopes utilizing deconvolution and 3D imaging techniques, the P-737 PIFOC® specimen piezo Z-stage features up to 250 µm travel, millisecond responsiveness and nanometer precise motion under closed-loop control.

High resolution 3D-Microscopy / Z-stack Image Acquisition: How it Works
The PIFOC® units are ideal for high speed Z-stack image acquisition, the basis for the generation of 3-D views of samples in high-resolution, optical microscopes. Conventional Z-drives use a motorized actuator and motor controller to create numerous focus planes during focusing. The individual “slices” are then processed with special software to form one 3-D image. PIFOC® systems are compatible with all major image acquisition packages.

Faster and Higher Resolution with Piezo
Piezo-actuated Z-drives, can achieve significantly higher focusing speed (typically 5 to 10 msec vs. 100 to 500 msec) and resolution (typically 1 nm vs. 0.1 µm) than stepper motor-drives and thus provide higher-quality images in less time.

Piezo Z-Stages and Objective Steppers
The P-737 PIFOC® piezo-stage is an addition to the extremely successful PIFOC® brand of high-speed Piezo objective Z-steppers. While no sample stage can beat the speed of the fastest PIFOC® objective positioners (due to the stiffer, more compact design), the P-737 PIFOC® stage allows for convenient Z-stack imaging with multiple objectives and very high throughput.

Piezo Z-Stages vs. Conventional Stepper Focus Drives
The fast response of the P-737 piezostage fully utilizes the high throughput of the latest digital imaging systems and achieves 20 to 50 times faster response than conventional stepper motor focus drives.

The P-737 PIFOC® stage is available with a number of analog and highly sophisticated digital piezostage controllers and can be controlled through digital interfaces as well as by fast analog signals through a high-speed 0-10V input. The system is fully compatible with all leading imaging acquisition packages. For ease of integration, a comprehensive set of LabView drivers is included, even with the analog control option.

Application Examples
3D imaging, Z-stack acquisition, autofocusing, scanning and alignment tasks in microscopy, biotechnology.
